Cement Energy and Environment

The above modification was done to increase 5.0 RABH Performance : the gas volume handling capacity and to reduce Table No. 03 gas velocity at various locations in RASH to enhance the performance. Table No. 02 Gas Velocity at RABH Particular Before After Modification Modification Inlet duct 24m/sec 15m/sec Outlet duct 24m/sec 15m/sec Module inlet 21m/sec 11 m/sec Module outlet 17m/sec 8 m/sec RA duct 14m/sec 6 m/sec **Gas flow is 15,80,000 M3/hrs at 240 Deg C Particular Before After Differential pressure RASH fan power Modification Modification 206mmWG 155 mmWG 1672 KW 1486 KW The entire modification exercise is planned to carry out during annual shutdown between July- August 2016 with shutdown time to be one month and successfully executed the project within time schedule. Sanghi Industries has been able to achieve desired reduction in pressure drop across bag house by around 50 mmWG and consequent reduction in power drawn by Bag House Fan. This also is expected to improve bag life considerably. The new norms for emission related to Cement Industry also is being achieved with grate ease. 6.0 Conclusion : The intended modification has once again confirmed that efficiencies can be improved through extensive brain storming , effective team building and coordinated execution. We shall continue to explore options for improvement in the interest of the organization in particular and for the Nation in general. ••••• 3
